The Primary Structure Of Hemoglobins Of The Adult Jaguar (Panthera Onco, Carnivora), Aftab Ahmed, Meeno Jahan, Zafar H. Zaidi, Gerhard Braunitzer, Reinhard Göltenboth

Pharmacy Faculty Articles and Research

The primary structure of the hemoglobins from Jaguar (Panthera onco) are presented. Electrophoretic separations without and with a dissociating agent revealed the presence of two hemoglobin components, OL2ß\ and a2 02. The separation of the hemoglobin components was achieved by ion-exchange chromatography. The globin chains were separated by ion-exchange chromatography and also by reversed phase HPLC. The amino-acid sequences of the native chains and peptides were determined by liquid-phase and gas-phase sequencing. N-Acetylserine was detected by FAB-mass spectroscopy as N-terminal group of the ßl chain. The sequences are compared with that of human hemoglobin (Hb A).

The Computer As A Collection Management Tool, Suzanne B. Mclaren, Hugh H. Genoways, Duane A. Schlitter

University of Nebraska State Museum: Mammalogy Papers

Since the mid-1960s, discussion of computer use for information retrieval in museum collections has usually focused on research potential. Much attention has been given to the idea of networking and the ability to access data across great distances. However, the potential for collection management usage has also proven to be a legitimate rationale for computerization. Numerous aspects of collection management are discussed for which the computer may be employed. Topics include creating cross-reference files, updating taxonomic and geographic information, pinpointing mismatched specimens, locating lost and uncataloged material, controlling loan procedures, producing accession files for insurance purposes, curating all or part …

Distribution And Current Status Of The Threatened Dismal Swamp Southeastern Shrew, Sorex Longirostris Fisheri, Robert K. Rose, Roger K. Everton, Thomas M. Padgett

Biological Sciences Faculty Publications

The Dismal Swamp southeastern shrew, Sorex longirostris fisheri, was given "Threatened" status by the U.S. Fish and Wildlife Service in 1986 because of its limited distribution and the potential threat of interbreeding with the nearby upland subspecies, Sorex l. longirostris. Known from about 20 specimens collected before 1980 and a few dozen taken since then, "fisheri" seems to have morphologically diverged from the smaller upland "longirostris" in association with the development of the Dismal Swamp. The detection of southeastern shrews that are intermediate in size between the two subspecies, coupled with the location of these collection sites on …

Fur Trade Records From Arkansas Factory, Arkansas Post, Louisiana Territory, 1805-1810, Paul J. Polechla Jr.

Journal of the Arkansas Academy of Science

The United States government established a trading house at Arkansas Post in 1805 on the north bank of the Arkansas River in the newly purchased Louisiana Territory. The goal of this trading house was to foster good relations with the Quapaw tribe and other indigenous peoples. John B. Treat and his successors operated the post and meticulously recorded the number, value, and species of pelts traded. Tabulation of these records, which have been preserved in the National Archives, revealed that 9 or 10 species contributed a total of about 44,000 hides, worth approximately $18,000. White-tailed deer (Odocoileus virginianus) pelts comprised …

The Identification Of The Threatened Southeastern Shrew Using Multivariate Statistical Techniques, Thomas M. Padgett, Roger K. Everton, Robert K. Rose

Biological Sciences Faculty Publications

The threatened subspecies of the southeastern shrew, Sorex longirostris fisheri, is endemic to the Great Dismal Swamp of southeastern Virginia. Previous studies based on discriminant analysis of external measurements determined that intergrades with the upland form, Sorex l. longirostris, exist along the periphery of the Swamp. To better discriminate among these populations, a study of cranial morphology was initiated. Fifteen cranial measurements were taken, using 59 specimens of Sorex collected previously form southeastern Virginia, including the Dismal Swamp. Both Principal Component and Cluster Analyses revealed no significant cranial variation or morphometric patterns within the specimens examined, but a …

Morphological Variation, Karyology, And Systematic Relationships Of Heteromys Gaumeri (Rodentia: Heteromyidae), Mark D. Engstrom, Hugh H. Genoways, Priscilla K. Tucker

University of Nebraska State Museum: Mammalogy Papers

Morphological variation was assessed within and among populations of Heteromys gaumeri using univariate and multivariate statistical analyses of external and cranial measurements. Although patterns and amount of nongeographic variation in H. gaumeri were similar to other heteromyines, geographic variation was relatively conservative. Mean values of most characters were statistically homogeneous among localities and spatially unpatterned. Consequently, no association was found between levels of within- and among-sample variation for individual characters (the "Kluge-Kerfoot phenomenon"). Populations of H. gaumeri were chromosomally monomorphic. The lack of morphological and chromosomal variation in H. gaumeri contrasts sharply with patterns in other heteromyines. Heteromys gaumeri is …

The Effects Of Xanthine And Adenosine Analogs On Rat Pup Diaphragmatic Contractility, Liam C. Farrell

Masters Theses

Methylxanthines are commonly used in the treatment of respiratory disorders such as asthma, apnea of prematurity and Cheyne-Stokes respiration. Recently, certain methylxanthines have been found to potentiate the contraction of the diaphragm and increase contraction strength of the fatigued diaphragm. The mechanism of action of the methylxanthines is unknown. Three theories have been proposed but each has its supportive and negative points. One theory is that methylxanthines inhibit cyclic AMP phosphodiesterase (PDE) which facilitates contraction by increasing cyclic AMP levels in the cell. Another theory is that methylxanthines antagonize adenosine, thus blocking the adenosine-induced inhibition of contraction. The third theory …

Revised Checklist Of North American Mammals North Of Mexico, 1986, J. Knox Jones Jr., Dilford C. Carter, Hugh H. Genoways, Robert S. Hoffmann, Dale W. Rice, Clyde Jones

University of Nebraska State Museum: Mammalogy Papers

As in previous lists, orders, families, and genera are listed in conventional phylogenetic sequence mostly following Hall (1981) but, in a departure from previous lists, species are entered alphabetically within each genus. This will facilitate use of the checklist by those unfamiliar with intrageneric taxonomy. Some assemblages are not well enough understood to create a meaningful hierarchy at the specific level.

“On Our Nebraska Records," Revisited, Wayne J. Mollhoff

Nebraska Bird Review

At the second annual meeting of the NOU, Dr. Robert H. Wolcott, one of our founders, presented a paper titled “On Migration Records and On Our Nebraska Records” (Proc. NOU 2:69, 1901), which included a plea for better documentation. He said, in part, “These problems must be met and answered in a spirit of scientific accuracy, if our conclusions are to carry weight with those living outside our borders. We must know what we know and record only what we know we know. We must be open at all times to conviction, but at the same time we must …

Proximity Nesting: The Great Horned Owl And Red-Tailed Hawk, Steve Shupe

Nebraska Bird Review

Introduction: Forty-two nests of the Great Horned Owl (Bubo virginianus) and 78 nests of the Red-tailed Hawk (Buteo jamaieensis) were surveyed during a three-year ecological study (1982–84). In 11 instances nests of the two species overlapped the hunting areas of the other. Home ranges, in which most hunting takes place, have been defined by various authors (Miller, 1930; Baumgartner, 1939; Hagar, 1967). For this study Hawks and Owls nesting within one-half mile of each other were compared. The proximity nesting of these two species seemed likely to increase the possibility of predation upon the young of …

Writing A Documentation, Barbara L. Wilson

Nebraska Bird Review

As the previous article makes clear, the written documentation helps birdwatchers communicate clearly about unusual sightings. Preparing the report can even add to the excitement of the event as one settles into a comfortable chair with the field notes and paper, chortling “Wait ‘til they read about this!” Then one relives the whole experience while organizing one’s thoughts for writing. Those field notes are an important part of the process, for they keep small but critical details accurate. Train yourself to take some kind of notebook or paper into the field, though in a pinch the margin of a field …

Cassin’S Sparrow In Garden County, Thomas E. Labedz

Nebraska Bird Review

On 21 May 1986, while searching for evidence of breeding birds in atlas block 2G04 near Lisco, Garden County, Nebraska, I discovered a Cassin’s Sparrow (Aimophila cassinii). This sighting was at 5:20 PM Mountain Daylight Time, along the county road in the northeast corner of Section 11. I was driving slowly down the road and stopped to observe an odd sparrow. I nearly drove past, thinking it was another Grasshopper Sparrow (Ammodramus savannarum), which I had heard and seen all day. The sparrow, which appeared larger than a Grasshopper Sparrow, was perched on the low wire …

Sharp-Tailed Sandpiper And Ivory Gull Reported, Sandy Kovanda, Jim Kovanda, Bill Otto, Eldon Marsh, Barbara Marsh

SHARP-TAILED SANDPIPER. On 12 October 1986 we saw an unusual sandpiper, in company of three dowitchers, on the east side of Nebraska Highway 15, about half the distance between the Platte River and Octavia, Butler County. We thought the bird to be a juvenile Sharp-tailed Sandpiper (Calidris acuminata).

IVORY GULL. On 12 October 1986 we were birding six miles east and half a mile south of Brunswick, Antelope County. . . . We were sitting in our vehicle at the edge of the road, facing south, when a white gull appeared. . . . [W]e identified this bird …

Bears and Men: A Gathering, William Mills, 108 pp., 9¼ x 9¼, Algonquin Books of Chapel Hill, Chapel Hill, NC, cloth $24. 95. The author’s pictures, mostly of polar bears, but with a few of seals, arctic fox, men and their machine, and two of Ptarmigan, are probably more important than the text, which describes a trip out from Churchill in a tundra buggy towing a dormitory accommodation, both supposedly (but not too) bear-proof. The trip was organized for those who were interested in photographing polar bears under relatively natural conditions. In the course of the narrative the author …
